Example of Operators in java tutorials

 

Example: Java program for arithmetic operators on int variables

 Sam Sir

// program name Main013.java

// Java program for arithmetic operators on int variables

public class Main013

{

public static void main(String[] args)

{

int a,b; // declare two variable a and b as integer

a=10;

b=4;

System.out.printf(" a + b = %d \n",(a+b));

System.out.printf(" a - b = %d \n",(a-b));

System.out.printf(" a * b = %d \n",(a*b));

System.out.printf(" a / b = %d \n",(a/b));

System.out.printf(" a modulus b = %d",(a%b));

}

}

Output

a + b = 14

a - b = 6

a * b = 40

a / b = 2

a modulus b = 2

  • Note:- All though 10/4 should give you 2.5 answer for division operation, but as a and b variable is integer, the result is shown as 2 only.

 

Example: Java program for arithmetic operators on char variables

 Sam Sir

// program name Main014.java

// Java program for arithmetic operators on char variables

public class Main0

{

public static void main(String[] args)

{

char V1,V2; // declare two variable V1 and V2 as character

V1='A'; // Assign A to variable V1

V2='S'; // Assign S to variable V2

int v1=(int)V1;

int v2=(int)V2;

System.out.printf(" V1 = %c V2 = %c \n",V1,V2);

System.out.printf(" ASCII Value of V1 = %d V2 = %d \n",v1,v2);

System.out.printf(" V1 + V2 = %d \n",(v1+v2));

System.out.printf(" V1 V2 = %d \n",(v1-v2));

System.out.printf(" V1 * V2 = %d \n",(v1*v2));

System.out.printf(" V1 / V2 = %d \n",(v1/v2));

}

}

Output

V1 = A V2 = S

ASCII Value of V1 = 65 V2 = 83

 

V1 + V2 = 148

V1 V2 = -18

V1 * V2 = 5395

V1 / V2 = 0

 

 

Example: Java program for arithmetic operators on mixed variables

 Sam Sir

// program name Main015.java

// Java program for arithmetic operators on mixed variables

public class Main015

{

public static void main(String[] args)

{

int i = 10; // declare and assign 10 to integer varaiable i

char c = 'A'; // declare and assign A to character variable c

float f = 7.5F; // declare and assign 7.5 to float varaiable f

System.out.printf(" i + f = %f \n", i+f);

System.out.printf(" i + i = %d \n", i+i);

System.out.printf(" i + c = %d \n", i+c);

System.out.printf("( i + c) - (2 * f /5) = %f \n", ( i + c ) - (2*f/5) );

}

}

Output

i + f = 17.500000

i + i = 20

i + c = 75

( i + c) - (2 * f /5) = 72.000000


 

 

Example: Java program for unary pre and post increment and decrement

 Sam Sir

// program name Main016.java

// Java program for unary pre and post increment and decrement

public class Main016

{

public static void main(String[] args)

{

int v1,v2,v3,v4;

v1=v2=5;

v3=v4=10;

System.out.printf("v1 = %d \n",v1);

System.out.printf("v1 = %d \n",v1++); // post increment

System.out.printf("v1 = %d \n\n",v1);

 

System.out.printf("v2 = %d \n",v2);

System.out.printf("v2 = %d \n",++v2); // pre increment

System.out.printf("v2 = %d \n\n",v2);

 

System.out.printf("v3 = %d \n",v3);

System.out.printf("v3 = %d \n",v3--); // post decrement

System.out.printf("v3 = %d \n\n",v3);

 

System.out.printf("v4 = %d \n",v4);

System.out.printf("v4 = %d \n",--v4); // pre decrement

System.out.printf("v4 = %d \n",v4);

}

}

Output

v1 = 5

v1 = 5

v1 = 6

 

v2 = 5

v2 = 6

v2 = 6

 

v3 = 10

v3 = 10

v3 = 9

 

v4 = 10

v4 = 9

v4 = 9
